TEST MATERIAL
- Amount(s) applied: 0.5 g test material, pasted with 0.4 ml sesame oil
Duration of treatment / exposure:
The exposure period was 4 hours.
Observation period:
72 hours after removal of the patches.
Number of animals:
3 females
Details on study design:
About 24 h before the start of the study the hair in the dorsal region of the body of the animals was removed with an electric clipper over an area of ca. 25 cm2. Only animals with intact skin were used.
Each animal was treated with the test material, the substance was evenly distributed over the whole surface of a 2.5 cm x 2.5 cm cellulose patch on a piece of surgical plaster (specially produced by Beiersdorf AG). The plaster was fixed to the prepared skin area and then covered with a semi-occlusive bandage.
The exposure period was 4 h, after the exposure all remnants of the test material were carefully removed from the skin with warm tap water.
Examinations of the skin took place 30 - 60 min as well as 24, 48 and 72 h after removal of the patches.
Erythema, eschar formation and edema were evaluated numerically, acc. to the score of Draize. All other changes of the skin were recorded.

Amount / concentration applied:

Duration of treatment / exposure:

Observation period (in vivo):
72 h after administration of the test material
Number of animals or in vitro replicates:
3 females
Details on study design:
About 24 h before the start of the study the test eyes of all animals were examined under UV light for corneal lesions after instillation of one drop of a 0.01 % fluorescein-sodium solution. Only animals without ocular abnormalities were used for the study.
100 mg of the test material was administered once to the conjunctival sac of the left eyeof three animals. In each case the untreated eye served as control.
24 h after administration the treated eyes were washed out thoroughly with isotonic saline at approx. 37 °C.
The eyes were examined 1, 24, 48 and 72 h after administration of the test material. At 24 and 72 h, the eyes were further examined for corneal lesions under UV light after instillation of one drop of a 0.01 % fluorescein-sodium solution. Lesions in cornea, iris or conjunctivae were graded numerically acc. to Draize. All other changes or toxic effects were recorded when apparent.

One hour after administration the conjunctiva of one animal was very slightly swollen. Furthermore, all animals showed definitely injected blood vessels at one hour up to 48 h after administration. In addition to these observations, serious eye discharge discoloured by compound was noted. 72 h after administration all signs of irritation had disappeared.

Interpretation of results:
GHS criteria not met
Executive summary:

Slight signs of irritation (a mean score of 0.56 for 3 animals at 24 -48 -72 h for conjunctivae redness) were seen in the eyes of the rabbits which were fully reversible within 72 h under the experimental conditions chosen here. Therefore, the test material has not to be classified according to GHS- or EU criteria.

Additional information

Justification for classification or non-classification

Classification, Labelling, and Packaging Regulation (EC) No. 1272/2008

The available experimental test data are reliable and suitable for classification purposes under Regulation 1272/2008. A GLP-compliant OECD 404 study is available for skin irritation. A GLP-compliant OECD 405 study is available for eye irritation. In both studies, the scores for the test item treated tissues were below the thresholds for classification as an irritant as specified in Regulation (EC) No. 1272/2008, as amended for the seventh time in Regulation (EC) No 2015/1221. As a result the substance is not considered to be classified for skin or eye irritation.
